Part 5 - Exchange 2010 MWI (Message Waiting Indicator)
Existing Environment:
1 x Exchange 2007 SP2 (Mailbox)
1 x Exchange 2010 (CAS, Hub and UM)
1 x Exchange 2010 (Mailbox)
If you do not enable the MWI of your SIP trunk between your Exchange UM and CUCM, you will get this event log warning:
The Unified Messaging server failed to deliver the MWI notification '1/7 (unread/read)' for the UM-enabled mailbox '(3037b9d1-3554-45af-8a68-077e54104120)' associated with UM extension 'xxxxx'. Additional information: Microsoft.Exchange.UM.UMCommon.MwiNoTargetsAvailableException: There are no more targets available to send an MWI message for user .
To get it working, you need to do the following:
- Login to CUCM, go to System - Security Profile - SIP Trunk Security Profile
- Find the SIP Trunk Security Profile that is being used by the SIP trunk between Exchange UM and CUCM
- Edit it and make sure the option Accept Unsolicited Notification is enable and reset the trunk

Hello,
Thank you for sharing that with us.
Quick question:
Does Exchange 2010 send unsolicited SIP Notifies with MWI? Do you have any docs stating that?
Thanks
